Internet-based telemedicine: An empirical investigation of objective and subjective video quality

This study focuses on the Internet-based telemedicine with the goal of understanding the relationship between objective and subjective video qualitymeasures and the decisionmaking capability ofmedical professional using an ophthalmology video.Objective and subjective measures are calculated using PSNR and the perception of human viewers respectively. An emulated Internet testbed was created for experiments. Results indicate that jitter and delay have significant effect on the objective quality values. Subjective quality, on the other hand, not only depends on the same two factors, but also depends on which critical frames the provider is able to see and work with. © 2007 Elsevier B.V.
